الانفال — Al-Anfal Ayat 73

وَالَّذِيْنَ كَفَرُوْا بَعْضُهُمْ اَوْلِيَاۤءُ بَعْضٍۗ اِلَّا تَفْعَلُوْهُ تَكُنْ فِتْنَةٌ فِى الْاَرْضِ وَفَسَادٌ كَبِيْرٌۗ

Wal-lażīna kafarū ba‘ḍuhum auliyā'u ba‘ḍ(in), illā taf‘alūhu takun fitnatun fil-arḍi wa fasādun kabīr(un).

"And those who disbelieved are allies of one another. If you do not do so, there will be fitnah on earth and great corruption."
